Resolves#13889
Adds support for exporting palettes in
Krita's .kpl format (zipped .xml data).
Colors are currently saved as 32-bit
floating point RGB values.
Future work includes supporting other
color spaces like CMYK, other precisions,
and including color profiles for colors.
Unlike the other bindings (Lua, JS, Vala) where we only have a demo
plug-in, we actually have a bunch of interesting and useful Python
plug-ins.
Furthermore, we are running several Python scripts through GIMP during
our build (to generate a few images), so pygobject becomes a build
dependency anyway, even if it may not be a run dependency with
-Dpython=disabled.
This all becomes a bit confusing and in fact handling this case (of not
installing Python plug-ins) seems like an annoyance while we lose good
core plug-ins. So let's just make Python plug-ins mandatory. It's not
like Python is very controversial these days, and AFAWK, it is available
on every platform out there.
Copied over from the original separate work in:
https://gitlab.gnome.org/Wormnest/gimp-file-plugin-tests
After that further improved and changed and added more file format
tests.
Added meson.build files to integrate it in our build, but we do not
install it for releases.
We compile GObject-Introspection anyway (except for cross-builds, where
anyway we don't rely on local Python scripts), so even if not installing
the Python plug-ins, still use them locally.
- Fix "no icons" errors generating loaders.cache with .cmd (CI-Cross).
! This is a sub-optimal fix, but it's better than a useless build.
- Fix "no interpreter" errors generating .interp with Meson (CI-Native)
and generating .interp and copying .typelib with .cmd (Local-Native).
! This is a sub-optimal fix to Local-Native, but plug-ins will work.
- Fix "no iso" error copying iso_639.xml with Meson (Local-Native).
… being installed.
There is already most of the main code logic for this, though now plug-ins need
to be in their own subdirectories, which breaks for plug-ins/common/ and
plug-ins/python/, while I needed plug-ins in both these categories to generate
the Windows installer welcome images (file-png, and python-fu-eval in
particular).
Once again, meson was not very helpful, since all its functions still refuse to
output generated files in subdirectories, so I end up duplicating plug-in files
with a custom Python script.
This should fix the CI. It was working on my machine as GIMP was installed, but
such a build rule should work even without GIMP installed.
This will also be useful in the future when we'll want to run unit tests of
plug-ins through the finale GIMP binary itself.
So procedures can declare args and GimpProcedureDialog show chooser
widgets
Fix so is no error dialog on id_is_valid for resources
Palette.pdb changes and testing
Memory mgt changes
Gradient pdb
Font and Pattern tests
Test brush, palette
Cleanup, remove generator
Rebase, edit docs, install test-dialog.py
Whitespace, and fix failed distcheck
Fix some clang-format, fix fail distcheck
Fix distcheck
Cleanup from review Jehan
Now that we bumped our meson requirement, meson is complaining about
several features now deprecated even in the minimum required meson
version:
s/meson.source_root/meson.project_source_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.source_root. use meson.project_source_root() or meson.global_source_root() instead.
s/meson.build_root/meson.project_build_root/ to fix:

Fixing using path() on xdg_email and python ExternalProgram variables:

fix:

We did port it to the new API but we are doubting it is useful at all.
It might have been, historically, when foreground extract algorithm was
first introduced, but probably not anymore, even more as the algorithm
is now implemented mostly on GEGL side anyway. So if any benchmark were
to be done, it should probably be added as GEGL tests.
Also as we are planning to update even more the API lately, it feels
really like a waste of time to also fix this plug-in while we currently
believe it to be useless.
Still we move it to the gimp-data-extras repository for being able to
easily bring it back in case we missed some use.
Per polls on Twitter, Reddit, Patreon and Tipeee, most people were
willing to drop this plug-in as not being relevant anymore (247 for
dropping and 63 for keeping it, so nearly 80% out of 310 participants).
So let's move it to gimp-data-extras allowing it to still have a
possible life, and who knows, maybe to even evolve.
See also corresponding commit beffc6b to gimp-data-extras repository.
shadow_bevel.py and sphere.py are unfinished and have been in the
"Unstable" only builds for years. This is probably not worth porting
them. Let's just delete them.
I have actually move these (as well clothify and whirlpinch removed
yesterday) to the gimp-data-extras repository so if anyone wants to
revive them, and port them to GIMP 3, they can start off from there.
Following Elad Shahar advice (cf. #4368), let's delete whirlpinch.py and
clothify.py.
The rational is that whirlpinch.py does the same thing as the existing
"plug-in-whirl-pinch" which is itself a compat plug-in to
"gegl:whirl-pinch" operation. Also the Python file has an explicit
command saying it is exactly the same algorithm, yet with no preview and
slower. Finally it was not even installed on stable build. It doesn't
look like there is any reason to keep it (it was probably a demo/test
Python plug-in).
As for clothify.py, a quick look at the short code shows it is exactly
the same algorithm as clothify.scm, with the same arguments and
installed on the same `Filters > Artistic` menu (except that the Python
version is not installed on stable builds).
So let's just keep the script-fu version as it has been the used version
until now, and there is no deprecation going on in one side or another.
So let's keep what already works.
Note by reviewer (Jehan): merging this port as it was in GIMP 2.10
anyway, but is this even still needed code? This plug-in is not even
available on stable release, it looks like for-development only
benchmark, and I'm not sure if it's relevant anymore, especially in our
GEGL-fueled new world.
Please anyone who knows a bit more on the history of this plug-in and
the evolution of our gimp_drawable_foreground_extract() algorithm, feel
free to weigh in and tell us what this was for exactly and if it's still
relevant.
This is a basic port without any UI.
Invoking the plugin will just sort the entire palette based on
default parameters.
The original plugin had several broken options, which I tried to fix.
Without the write permission for the owner, the `make install-plug-ins`
special target fails on Python plug-ins. And anyway I don't see a reason
why not give write permission to the owner (like all other plug-ins are
installed).
